This invention relates generally to improvements in identification appliances such as wristbands and the like for mounting onto a specific person or object, and for carrying information associated with the specific band wearer. More particularly, this invention relates to an improved identification bracelet having a sealable window for overlying and protecting wearer-related information applied to or carried by the bracelet against contact with moisture and the like for an extended period of time, wherein such moisture contact could otherwise interfere with or adversely impact human and/or machine reading of the wearer-related information.
Bracelet-type identification appliances such as wristbands and the like are commonly worn by individual patients in a hospital or other medical facility. The identification bracelet normally carries certain human-readable patient identification information such as patient name, room number, patient identification (ID) number, etc., wherein this identification information can be printed directly onto the bracelet, or otherwise applied to a card, tag or label that is affixed to or suitably carried by the bracelet. In addition, a variety of machine-readable information may be similarly applied to or carried by the bracelet, such as bar code information which may duplicate the human-readable patient identification information but may also include selected patient condition information. In recent years, such identification bracelets have also incorporated radio frequency identification (RFID) circuits having the capacity to receive and store significant patient medical history in addition to patent identification and condition information. Such identification bracelets have also been used in a wide range of non-medical environments.
Moisture contact with the wearer-related information carried by the identification bracelet can interfere with and thereby prevent accurate reading thereof by human or automated means. In this regard, some bracelet designs have incorporated a transparent window element to overlie and thereby provide some protection for wearer-related information visible through the transparent window. For example, U.S. Pat. Nos. 4,221,063; 4,285,146; 4,318,234; 4,386,795; and 5,581,924 depict a bracelet wherein a transparent window element cooperates with an underlying band to define a small slotted pocket for slide-fit reception of a card, tag or label having the wearer-related information printed thereon and viewable through the window element. However, many of these bracelet designs provide only limited protection, and, more specifically, are not sealed against water intrusion upon immersion of the bracelet as may occur, for example, during bathing.
Alternative bracelet configurations have been proposed wherein the transparent window element is backed with a transparent, typically pressure-sensitive adhesive layer. See, for example, U.S. Pat. Nos. 3,197,899 and 6,546,656 which depict the transparent window element adhesively positioned over an information-bearing zone or region formed on or carried by an underlying flexible band. The transparent window element is initially adhered at one end to the underlying band and thus comprises a movable flap that can be lifted to expose the information-bearing zone, and further to permit a peel-off film to be removed from the flap before downward displacement into adhered relation with the band in a position overlying the information-bearing zone. Hermetic sealing of the periphery of the information-bearing zone, however, is at best limited to provide minimal protection against water intrusion. In addition, in these bracelet designs, the movable flap is incompatible with convenient and economical manufacturing methods particularly such as producing a plurality of ready-to-use bracelets in a snap-apart or break-apart sheet form. Moreover, the transparent window element in these designs is combined with fastener means for adhesively mounting the bracelet about the wearer's wrist or the like, resulting in a complex bracelet construction with limited inherent variable size adjustment capability.
U.S. Pat. No. 5,740,623 describes another alternative bracelet construction including a tubular band formed from transparent plastic, and defining an internal pocket for slide-fit reception of an information-bearing card, tag or label, with a connector element provided for press-fit reception into the opposite ends of the band to form and retain the band into a closed loop configuration wrapped about a person's wrist or the like. While this bracelet design may provide improved hermetic protection against ingress or moisture or other liquids into contact with the information-bearing card or the like, the tubular band construction does not provide inherent size adjustment capability. In addition, the tubular band construction is also not susceptible to convenient and economical manufacturing methods particularly such as producing a plurality of ready-to-use bracelets in snap-apart or break-apart sheet form.
There exists, therefore, a significant need for further improvements in and to identification bracelets of the type used in a medical facility and the like, particularly wherein a transparent window element is mounted onto an underlying flexible band in a manner conducive to economical manufacture in multi-bracelet sheet form, and further wherein a transparent window element is adapted to overlie and hermetically seal underlying wearer-related information against contact with moisture and the like. The present invention fulfills these needs and provides further related advantages.
In accordance with the invention, an improved identification bracelet is provided for mounting about a person's wrist or the like, and includes a sealable window to protect wearer-related information against potentially damaging contact with moisture and the like, wherein such moisture contact can interfere with or adversely impact human and/or machine reading of the wearer-related information. The improved bracelet is designed for economical manufacture in a convenient sheet form including multiple bracelets adapted for snap-apart separation from the sheet in a ready-to-use state, or in an end-to-end roll form.
In one preferred form, the identification bracelet comprises an elongated flexible band constructed from a moisture-resistant material to include an information-bearing zone adapted to receive and support wearer-related information such as information printed or written directly thereon, or information applied to a card, tag or label positioned thereon. A transparent, adhesive-backed cover strip spans the information-bearing zone in overlying relation thereto, with opposite ends of the cover strip securely adhered to the underlying band generally at opposite ends of the information-bearing zone. This central window segment is initially separated or easily separable from the underlying band, as by means of a peel-off release film on the underside of the cover strip.
At the time of use, one end of the cover strip central window segment is adapted for lift-away separation from the flexible band, as by tearing the cover strip along a line of weakness such as a perforation line formed therein at a position generally overlying one end of the information-bearing zone on the band. This now-separated end of the cover strip central window segment can be raised relative to the flexible band to expose the information-bearing zone for receiving the wearer-related information, and also for exposing the release film on the underside of the central window segment for peel-off removal. The central window segment can then be pressed downwardly onto the band, into firmly seated and sealed adherence therewith. The cover strip central window segment and the flexible band cooperatively define an hermetically sealed perimeter circumscribing the wearer-related information to safeguard such information against subsequent contact with moisture and the like, thereby safeguarding the information for reliable and accurate reading by human and/or machine means.
The identification bracelet further includes fastener means for retaining the elongated band in a closed loop configuration of selected diametric size wrapped about the wrist or the like of a person or object associated therewith. In one preferred form, the fastener means includes interengageable fastener elements at opposite ends of the flexible band, and preferably independent of the information-bearing zone on the band, such as snap-fit engageable male and female components at one end of the band for engagement with one of a longitudinally spaced-apart series of fastener ports formed in the other end of the band, as disclosed in U.S. Pat. No. 5,581,924 which is incorporated by reference herein. Alternative fastening elements such as adhesive fastening means and the like may be used.
Other features and advantages of the invention will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.
The accompanying drawings illustrate the invention. In such drawings:
As shown in the exemplary drawings, an improved identification bracelet referred to generally by the reference numeral 10 is provided for mounting in a closed loop configuration (
Information-bearing identification bracelets and the like are widely used in a number of applications wherein a convenient and lightweight, relatively inobtrusive identification appliance is desired for use in verifying the identity and/or other key information pertaining to a person or object to whom the bracelet is attached. As one key example, such identification bracelets are well known for use in a hospital or other medical facility to identify an individual patient. That is, wearer-related information such as patient name, etc., is applied to the bracelet which is then affixed about the wrist or the like of the associated patient. The wearer-related information may be applied in human-readable written, typed or printed form, and/or such information may be applied in a machine-readable format such as bar code or by means of memory circuits such as radio frequency identification (RFID) devices. The use of machine-readable formats beneficially expands the volume and type of information, such as patient medical records and/or patient condition information, that can be inputted to and subsequently read from the identification bracelet.
The improved identification bracelet 10 of the present invention beneficially accommodates a wide range of wearer-related information applied directly to the bracelet, or otherwise mounted onto the bracelet as by means of a card, tag or label 18 (
As shown generally in
The illustrative drawings show the first band end 24 to include fastener means such as snap-fit engageable male and female fastener components 28 and 30 adapted to interlock through a selected one of a series of longitudinally spaced fastener ports 32 formed in the second band end 26, as shown and described in more detail in U.S. Pat. No. 5,581,924 which is incorporated by reference herein. Such fastener components are beneficially designed for self-locking, and effectively permit removal of the bracelet 10 from a person's wrist or the like only by cutting and destroying the bracelet. Persons skilled in the art will recognize and appreciate that a variety of different fastener means and fastener constructions, such as adhesive fastener elements, and alternative mechanical fastener elements, may be used.
A transparent cover strip 34 is mounted onto the flexible band 20 in a position extending over or spanning the information-bearing zone 22 on the band. This transparent cover strip 34 is also formed from a lightweight and water-resistant or water-impervious and substantially transparent material such as a plastic film, and, in the preferred form, is backed by a thin layer of a transparent adhesive material such as a pressure-sensitive adhesive. In an initial configuration, opposite ends 36 and 38 of the adhesive-backed cover strip 34 are securely adhered to the flexible band 20 respectively at opposite ends of the underlying information-bearing zone 22. However, a central region of the cover strip 34, defining a transparent central window segment 40, is initially separated or spaced from the band and thus is not adhered thereto, by means of a thin peel-off paper-based release film 42. Thus, in the initial as-constructed configuration, the cover strip 34 has both ends firmly connected by the adhesive backing to the band 20 at opposite ends of the information-bearing zone 22, with the peel-off release film 42 separating the central window segment 40 from the underlying information-bearing zone 22 on the band 20. This initial as-constructed configuration is particularly suitable for convenient and economical production in the sheet form 14 as viewed in
With the window segment 40 in the raised position, the peel-off release paper-based film 42 is substantially exposed for easy access and removal (
Persons skilled in the art will recognize and appreciate that alternative forms of the invention may be employed to achieve the desired moisture-impermeable hermetic seal perimeter circumscribing the wearer-related information 12 on the information-bearing zone 22 of the band 20. For example, in lieu of the pressure sensitive adhesive and peel-off release film 42 initially underlying the transparent central window segment 40, other techniques such as heat sealing of the central window segment 40 onto the underlying band 20 following placement of the wearer-related information 12 on the zone 22 may be used.
In use, the bracelet 10 thus incorporates the wearer-related information 12 viewable through the transparent central window segment 40. Importantly, this window segment 40 comprising a laminating element which cooperates with the underlying band 20 to hermetically encase the wearer-related information 12 on the information-bearing zone 22 is a manner that is protected against moisture ingress. The hermetic seal perimeter circumscribing the wearer-related information is sufficiently flexible to accommodate normal bending and use of the bracelet 10 in a closed loop configuration (
In use, the adhered end 238 of the cover strip 234 can be lifted and separated from the underlying band 220, as viewed in
Accordingly, the alternative embodiment shown in
More specifically,
The cover strip-forming material 134 is drawn from the supply reel 62 over suitable guide reels 66 and 68 which guide and press the material 134 onto the underlying band-forming material 114. Importantly, thin edge strips 70 and 72 of the release layer 142 are separated from the material 134 by a waste roller 74, so that the opposite edges of the material 134 are pressed into secure adhered engagement with the band-forming material 114. These adhered opposite edges of the cover strip-forming material 134 correspond with the opposite ends 36, 38 of each cover strip 34, with the remaining central portion of the release layer 142 corresponding with the release film 42, all as previously shown and described herein.
From the laminating station 60, the partially underlying band-forming material 114 and the overlying cover strip-forming material 134 are drawn or transported further through a sequence of die cutting stations, such as an outline die station 76 for cutting the underlying material into the outline shape of a succession of individual bracelets 10 separable along adjoining lines of weakness such as perforations 44, and a hole cutting station 78 for cutting multiple fastener ports 32 in each bracelet 10. An additional perforation die station 80 then forms the line of weakness such as the perforation 48 between the central window segment 40 and one adhesively anchored end 38 of each cover strip 34. Although rotary die elements are shown, it will be understood that other types of die elements, including non-rotary die elements, may be used.
A waste web station 82 separates any remaining marginal material from the elongated succession of bracelets 10 which can then be formed into the desired multi-bracelet sheets 14.
Irrespective of the production process and direction, i.e., side-by-side in multi-bracelet sheet form as viewed in
A variety of further modifications and improvements in and to the identification bracelet 10 of the present invention will be apparent to persons skilled in the art. Accordingly, no limitation on the invention is intended by the foregoing description and accompanying drawings, except as set forth in the appended claims.
